QUESTION 9

         Two brothers walk into a seafood restaurant and each orders the swordfish special. The older brother, who weighs twice that of his younger brother, orders the 16-ounce Mega-Hungry portion. The younger brother orders the smaller 8-ounce portion and cautions his older brother that he should be careful how much he eats since swordfish contains mercury. The older brother scoffs and declares that he is receiving the same toxicological dose. The younger brother disagrees,saying \"you\'re eating twice as much, you hog\".  Presuming their meals derived from the same fish, which brother is correct?   

         Older brother (maybe)

         Younger brother

         Neither

         Cannot determine with information provided
